WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 764,440, dated July 5, 1904.

Application filed October 31,1903.

To all whmn it may concern.-

Be it known that I, WALTER E. ELLIS, acitizen of the United States, residing at 447 Bnte street, Norfolk, in the county of Norfolk and State of Virginia, have invented new and useful Improvements in Window Screens, of which the following is a specification.

My invention relates to new and useful improvements 'inwindow-screens; and its object is to provide an adjustable device of this character which is durable in construction and can be readily folded to form a compact bundle which may be conveniently stored when not in use.

The invention also consists in so constructing the screen as to render the same adjustable Without the necessity of employing crossbars such as are ordinarily used and which 01)- struct the vision.

With the above and other objects in view the invention consists in providing a screen the upper and lower bars of which are preferably hinged, so as to permit them tobe folded, and to these bars are fastened the opposite edges of a suitable netting. The ends of the bars are slotted for the reception of ribs, which are formed upon sliding arms extending laterally from end bars. Strips of netting are connected to the end bars and their respective arms and are adapted to overlap the netting connected to the top bars. Means are provided whereby the sliding arms can be locked in adjusted position, and guide-cleats are also preferably provided for use in connection with the screen.

The invention also consists in the novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a front elevation of the screen in position within a window-frame. Fig. 2 is a rear elevation thereof detached. Fig. 3- is a perspective view of a portion of the screen and one of the adjustable sections, the same being detached. Fig. 4 is a plan view of a portion of the top bar and one of its adjustable arms, the same being partly shown in Serial No. 179,372. ,(No model.)

section. Fig. 5 is a perspective view of the screen folded, and Fig. 6 is a detail view of a portion of one of the folding cleats.

Referringto the figures by numerals of reference, 1 1 are the top and bottom bars of the screen, the same being connected to the upper and lower edges of a netting 3, formed of wire or other suitable material. Each of the bars 1 is preferably constructed of two sections, which are connected by means of hinges t, whereby the screen maybe readily folded along the center thereof for convenience in storage. The outer face of each bar 1 is slotted longitudinally adjacent each end, as shown at 5, said slots being shaped to receive dovetailed beads 6, arranged longitudinally upon arms 7, which extend laterally from end bars 8. These arms 7 have slots 9 extending longitudinally therein for the reception of bolts 10, which are fastened to the bars 1, and have thumb-n uts 11 arranged thereon for clamping the arms 7 to the bars 1. The beads 6 extend. the entire length of the arms 7, and the slots 9 are located between the ends of the beads and the free ends of the arms. Strips of netting 12 are fastened to the end bars 8 and to the beads 6 adjacent thereto, and these strips base-strips 15, adapted to be secured to the wmdow-frame in any suitable manner. These cleats are preferably formed in sections hinged together, as shown at 16, and each section being equal in length to the height of the screen.

In placing the screen within a windowframe' the ends 11 are unscrewed, so as topermit the arms 7 to readily slide upon the bars 1. Said arms are then pressed inward, so as to permit the end bars 8 to be readily placed within the window-frame and upon the cleats 14, which have previously been fastened in position in said frame. The end bars 8 are then moved outward, so as to firmly engage the cleats,'and arms 7 are secured in adjusted position by means of the nuts 11 on the bolts 10. After this adjustment has been made the overlapping edges of the netting 3 and the strips 12 are laced together by means of fine WIIBS 17 01' in any other suitable manner, and flies, mosquitoes, and other insects are thus prevented from entering between the overlapping edges. Any suitable means (not shown) may be provided for preventing the screen folding upon the hinges 4 when the same is in use. When it is desired to store the screen, it can be folded into a compact bundle by sliding the end bars 8 inward and by folding the bars 1 upon their hinges.

In the foregoing description I have shown the preferred form of my invention; butI do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus fully described my invention, what I therefore claim as new, and desire to secure by Letters Patent, is

1. In a screen, the combination with oppositely-slotted bars and netting connecting the bars; of end bars, laterally-extending arms thereon, ribs upon the arms and adapted to engage the slotted bars, means for adjustably connecting the arms to the slotted bars, and netting secured to the end bars and the ribs and adapted to overlap the netting on the slotted bars. N

2. In a screen, the combination with oppositely-arranged, slotted bars and netting connecting the same; of end bars, arms extending therefrom and adj ustably secured to the slotted bars, netting secured to the end bars and their arms and overlapping the netting on the slotted bars and means for securing the netting together.

3. In a screen, the combination with oppositely-arranged slotted bars formed of hinged sections, and netting connecting the bars; of end bars, arms extending therefrom, ribs upon the arms and projecting into the slots in the first-mentioned bars, means for securing the arms in adjusted positions and netting secured to the end bars and the ribs and adapted to overlap the netting on the slotted bars.

4;. In a screen, the combination with oppositely-arranged slotted bars formed of hinged sections, and netting connecting the bars; of end bars, laterally-extending arms thereon, ribs upon the arms and adapted to engage the slotted bars, means for adjustably connecting the arms to the slotted bars, netting secured to the end bars and the ribs and adapted to overlap the netting on the slotted bars and means for securing the overlapping edges of the netting together.

5. In a screen the combination with oppositely-arranged slotted bars formed of hinged sections and netting connecting the bars; of end bars, laterally-extending slotted arms thereon, ribs upon the arms adapted to en gage the slotted bars, clamping means adjustably connecting the arms to the slotted bars, netting secured to the end bars and the ribs and adapted to overlap the netting on the slotted bars and means for securing the overlapping edges of the netting together.

In testimony whereof I afiix my signature in presence of two witnesses.
